Hi Gatiana, we’ve put this question out on Twitter this afternoon. Let me know if you’re not on it or can’t access it and I’ll relay any answers we get. So far this place has been recommended for vegans:

Oh I will surely love this place! I love veggies too much even though I’m not yet a full pledge vegan. My suggestion is keep in mind all the benefits that veggies can give to you. List it down and remind yourself how healthy you will become.

There is a place called Had-dra, which basically means, the Sunday Market.
You will find Had-dra on the way to Essaouira, a must see place.
At Had-dra, you will find one of the most amazing markets this planet has to offer, and with that, all the fresh, chemical free vegetables and fruit possible for your traveling time of year.
